That's an interesting question. I might be wrong, but I don't think there are any regulations in regard to how much material is used. Each design is different and requires a different amount of material so I don't think they can say 'x yards for Crown Princesses and y yards for princesses, etc'.

I don't know if it's a 'rule', but most of the royal brides wear floor-length gowns just because the weddings are normally very formal. Shorter dresses (i.e. above the ankle) are normally for weddings that are less formal. A lot of brides have a train so it would be kind of weird if you had one with a shorter dress. Hope this helps!

Hi Danielle, thank you for your answer!

I know that almost all of royal brides have a long train. So is there any rules for the length of the train? or the train can be as long as you like?

Does anyone know: How long are the wedding gown trains of the royal brides?

I've always wanted someone to explain to me what the prestige is of these super long trains. Personally, I think they look ridiculous and sometimes downright ugly. Mary of Denmark dragged this ugly blanket of plain fabric behind her that seemed to have little to do with the rest of the dress. What does it prove? We already know they have lots of money - a few more yards of silk can't be that big a deal.

It's not that I dislike trains in general. The picture of Princess Grace at the "Royal Wedding Gowns" site linked above shows a train fanned out behind her in perfect proportion to the rest of the dress.

I just don't understand why so many people are impressed just because a piece of fabric is 20 feet long instead of 15.

Principessa, this is the Wedding page from the official website; and this is the page for the gown.
It says that the train was 6m long measured from the waste, and was made of 23.5 metres of duchess satin.

The purpose of a train on a Royal wedding gown-I think-is to add scope and majesty to what would otherwise be an ordinary gown. Also most Royal weddings take place in enormous cathedrals or churches. A train added to a gown is needed to "fill out" empty space. In medieval times, the longer the train attached to a lady's gown the higher her status was. Commoner women did not have trains, it was the prerogative of a noblewoman only.
